The Environmental Center was established in 1970 by the students who organized the first Earth Day at CU. It has grown to be the largest student run environmental center in the country and a model to many others. Thirteen permanent staff support the work of the student board, volunteers, and student employees. This section of our website further explores who we are and what we do at the "E-Center."
